.lateuted Apznfi, 1915.

Application filed June 28. 1913. Serial No. 776.228.

of Trenton, Mercer county. in the State of New Jersey, have invented an Improvement in Caps for Automobile-Radiators and the like, of which the following ale seription, in connection with the uecoinpanying drawings a specification, like letters on the drawings representing like parts.

The object of the invention is to proi'irle, at less expense than has been. possible here tofore, a cap for automobile radiators and: other'cleriees, of the type which has terior core-ring of hard rubber or the mohied about which is to the pin The ini'enti structing the that a minim: theprom t ably by the use of some such wen teriai "oahelite' or condone; 1 I stead of hard rubber. as the former afiecteci by the action of st am or ii: and therefore may he the interior of the. railia. ternosit on. cf un ll ent ini'enlio-zi. the .niouui oi' in considera lin r-ii. w

is employer n .1.

In the drawings, l hare illustrated practical euihm liinenf f my invention: inal as there. shown Figure l is a plan new Fig. 9 is a View in ce' "l vertical s showing the cap in pi. .150 on the top o the rudiah'ir pipe. i i is a perspective view of n threinleti bushing removed from the cap, and Fig. -1- is 11 plan view of a ring: removed "from the cap, which ring forms an annular shoulder at the top oi the hushing when the parts are assembled.

The bushing referred to above is denoted by .e'ancl may readily he formed irom thin nietallic brass piping by passing the same through an automatic threading iaehine and cutting the same oil to size. As now siderahly thicker than the present bushing. On the top of the cap is laid a top piece E which as shown in i i- -i. This ring may stamped out o? very thin'sheetoi brass anal shouhl he made of sufiieient dimensions to project inwardly across the opening of the bushing a. so as. to form an annular shoulder for the radiator pipe 0 to abut preferably in the form of a ring,

a ainsr when the cup is in position-(see' Fig. thus forming the top piece separately from the bushing, a much thinner piping may be used to produce the bushing for the reason that if the top piece be formed iitite gi ally with the bushing and 'eer a suiheient extent into the opening ti pining ouhl have to he much to start with.

The exterior covering as will be seen, exposed to the interior of the pipe 0, nuereas heretofore, a thickness of metal has i it from the space. inside the pipe r to prevent the deleterious action n or hot. water upon such covthe present case, therefore, the i here it exposed, consists of a. in. nhieh is not ai'l'cctcd by the action of steam. .Ul-flClmliflblG material for this purpose is either the well-known bakeli ior eonileusite which consist of a properly treated mixture of phenol and formall-yile. This nmterial is uiohled over the to}; and around the sides of the cap in any suitahle manner. the bushing being prefer- ;ilily provided with g ooves e to retain the same; and then the material is cured or :e bushing to form an abutment for the har h neil so as to form rigid impervious ('(li'i'l' around the ring and. bushing both of hieh it ll ll(i. in place.

lusteail of forming the top piece 6 as a ring. it may he formed as a very thin flat disk or conca e piece anii in this way will cover the in}: of the pipe (1 entirely. This latter.

,the like, comprising a threaded metalbush ing open at both ends and adapted to be screwed on to the end of a pipe, and a covering of hardened moldable material unaffected bythe action of steam or hot water and having a relatively high elastic limit,

the said covering surrounding the periphery and closing-one end of the bushing.

2. A cap for automobile radiators and the like, comprising a bushing adapted to fit; the part to which the cap is ,to be applied, a separate top piece upon the bushf' in'g projecting inwardly to a sufficient extentto form a shoulder for the said part to ahutgagainst and a covering of moldable material over the top and around the sides :andharde'ned so a'svto 'hold the bushing and ,top piece in position and to form arigid impel-nous cap.

V i .5. A cap tor-automobile radiators and the like, comprising a bushing adapted to fit the part to which the cap is to be ap plied and 0 en, at both ends, a covering of hard molda 1e material unaffected by. the

action of steam or hot water and having a relatively highelasti c limit, the" said .cov-

ering surrounding the "=p,er.iphery and c'los- 3 he applied.

4 In testimony whereof, I have signed'm'y ing one end of the bushing, and means to retain the cap on the part to ,Which it is to;

name to this specification, in theprescnce of two subscribingwitnesses, this 17th day I .of June, 1913.
